Question
we are currently using the „AD210JN“ as an input-amplifier in an industrial
automation project. However, we have some issues with the “Vo” (Pin 1) and
“Ocom” (Pin 2) output. We are trying to use add a constant offset of 1.65V to
the output of the OpAmp by connecting “Ocom” (Pin 2) with a constant voltage of
1.65V. However, when connected to the 1.65V offset-voltage, the “Vo” (Pin 1)
output generates only garbage (+- 500mV on its output).
So, my question is: Is it possible to add a constant output-offset to the AD210
output this way? Are there any other methods of adding an constant offset to
the output of the AD210?

Please find attached a sample Output adjustment circuit for reference.
